In this torrent, photovoltaic power generation technology is becoming a major research field because of its green, carbon free operation and efficient fit with architectural modeling.
03 TongZhou Contemporary Art Museum The “MoMA of contemporary TongZhou Wanguo city – Architecture & Art Museum” project is located in Wanguo home, Tongzhou District, Beijing, close to Yiyuan East Street.
At the same time, we use 10000 in Tongzhou District The addition of some solar modules in guojiayuan can achieve the design goal of net zero energy consumption of the whole building of the art museum.
The project adopts high air tightness insulation system, high efficiency photovoltaic power generation system, high adaptability Internet of things / Internet Intelligent Building / automatic control system.
The project generates electricity in photovoltaic Build a real and typical low-carbon green residential area in the form of electricity.
Dinosaur 3 roof is fully paved with heterojunction photovoltaic modules, with a size of 1645x985mm and a laying area of 90m2.
The power of single module is 315w, the total installed capacity is 17.64kw, and the light conversion rate can reach 23.7%, which is about 20% higher than that of conventional photovoltaic modules.
In addition, the project has also won many awards, such as Jingrui science and technology award issued by the Ministry of science and technology of the people’s Republic of China, international active building acitvehouse building science and Technology Innovation Award, top 10 green building models of China economic alliance in 2019 and so on.
02 dinosaur 3 The assembled net zero energy consumption combined unit building: Dinosaur 3, located in the contemporary time Lane project in Shunyi District, Beijing, is based on the aging model room, with the purpose of “green living and smart home”, equipped with high thermal insulation peripheral protection structure, high power generation efficiency photovoltaic system and high adaptability Internet of things intelligent home equipment.
Here, first Habitat also expects more enterprises to join the research and practice of green application of photovoltaic and other new energy, and jointly “realize beauty with science and technology and help low carbon with green” To create a beautiful home for green residential areas-.
The installed capacity of photovoltaic modules is 435kw and the annual power generation is about 500000 kwh.
Under the background of “double carbon” policy, green and low-carbon residential buildings will also become the main trend of residential building development in the future.
The practice of MoMA Architecture & Art Museum in Tongzhou contemporary Wanguo city will provide a valuable application case for the combination of net zero energy consumption and intelligent buildings in beijing.04 Xi’an contemporary government project Xi’an Xiandai mansion project is located in Chanhe West Road, Xi’an city.
The combination of solar photovoltaic power generation and residential buildings has good development prospects.
Based on the background of China’s “14th five year plan” energy development plan, dinosaur 3 perfectly combines the “national strategy of ‘actively responding to population aging’ with the” national strategy of ‘carbon neutralization’ and ‘carbon peak’, and sets a new benchmark for a green and intelligent elderly care community in the new era.
With an overall construction area of 1603 square meters, three floors above the ground and one floor underground, it is an urban complex integrating commerce, exhibition and leisure.
Based on this, first Habitat, together with contemporary real estate, began to try to gradually promote the pilot project construction of the combination of solar photovoltaic and residential and commercial buildings, so as to promote the low-carbon of residential projects.
The solar power generation capacity of the project is mainly used for power consumption in underground garages, public areas and other parts, so as to improve the proportion of green power consumption in the community.
Dinosaur 3 project has been selected into the national “13th five year plan” project, the near zero energy consumption building demonstration project in cold areas, the Sino US clean energy demonstration project, and has obtained the support of the national healthy building industry technology innovation strategic alliance healthy building fund.
However, according to the statistics of the national energy administration, China’s energy consumption has continued to break through a new high this year, in which the proportion of thermal power installed capacity is still increasing, which is still far from the policy requirements of “carbon neutralization and carbon peak”.
In 2020, based on the inherent requirements of promoting sustainable development and the responsibility of building a community with a shared future for mankind, China announced the vision of “carbon peak” and “carbon neutralization”.
The application practice of new energy in buildings is constantly emerging, and various technical explorations for the realization of low-carbon buildings are in full swing.
The photovoltaic system generates about 50kwh per day on average and 18300 kwh in the whole year.
Through the energy storage system, the reserve of photovoltaic power generation can be realized, and the energy storage system gives priority to providing power demand for indoor electrical equipment.
The carbon reduction is equivalent to planting 885 trees every year.
Meanwhile, dinosaur 3 is also equipped with energy storage equipment, with an energy storage system capacity of 5.7kwh.
The project uses the cornice of the building facade to lay thin-film solar photovoltaic modules.
By analogy, it saves about 5.4 tons of standard coal and 16.2 tons of carbon dioxide.
At present, the design phase of the project has been completed, and has obtained the “green building Samsung design logo”, “China passive ultra-low energy consumption green building logo”, the passive house certified by phi of Germany Passive House Research Institute, and the “China Germany cooperative high energy efficiency building passive low energy consumption building quality logo” certified by DENA of Germany Energy Agency “Beijing green building Samsung design logo, passive ultra-low energy consumption building certification” Certification and identification.
About 300 square meters of cadmium telluride thin film solar photovoltaic modules are set on the North-South slope roof of the building to provide auxiliary power for the overall building, and the annual power generation of the whole system is about 40000 kwh.
01 background As global climate change poses a major threat to human society, more and more countries have raised “carbon neutralization” as a national strategy and put forward the vision of a zero carbon future.
05 conclusion With the promulgation of the “dual control system plan” of the national development and Reform Commission in early September, major provinces and cities in China are facing a shortage of power supply resources.
The completion of dinosaur 3 has realized the organic combination of elderly care community and green residential area.
